ROB HANGER.

Application filed March 29, 19243. Serial No. 95,313.

This invention relates to new and useful improvements in a rod hanger.

One object of the Vinvention is to provide a device of the character described specially designed for the purpose ot'` suspending the pump rods ot' a well pump in the derriclr, and is of such construction that the rods may be readily attached to the hanger, pulled from the well and as readily detached therefrom, as made up in letting the same down into the well. v y y Another object oit the invention is to provide a novel type of rod hanger by means ot which the rods may be suspended in the derriclr in the Order in which they are separated, as brolren up, and may be reunited, in letting them back into the well, in the order ot their original positions in the'completed, or made up pump sucker rod. A further feature of the invention residesv in the provision of a hanger which is ot very simpleconstruction, may be cheaply and easily produced and through which the pump rods may be easily and expeditiously handled in pulling the same from, or letting the same down intofa well bore. v v

lVith the above and other objects in view this invention has particular relation to certain novel features ot construction, operation and arrangement ont parts, an example of which is given in this specification and illus- J tr-ated in the accompanying drawings, wherein Figure 1 shows a horizontal sectional view of a derricl, showing a-plan view'ot the im'- proved type of rod hanger mounted therein. Figure 2 shows a fragmentary vertical sectional view thereof, showing said rod hanger in section. i

Figure 3 shows an enlarged plan view of the hanger, and Figure 4 shows an enlarged side elevation thereof, partlyin sect-ion.

Referring new more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the ligures the numeral 1 designates the dei-rich, as a whole, which is ot conventional construction. ln the derrick there is a transverse -beam 2 whose ends are supported on the cross beams 3, 3, forming part et the derricl. rlfhe beam .2 is preferably Adisposed with its web in horizontal position and its end flanges resting upon the beams 3 and disposed vertically. The'beam 2 is disposed inthe derriclr to one side or', and above, the well 4 being pumped.

vthe lower iianges of the I-beam 2.

Formed integrally with each `bracket 6 i therel is a bar 9, one end of whichI extends out beyond .the corresponding arm 7 of said bracket and is formed into a hook 10 provided with a V-shaped notch 11, forming a rodengaging j aw. Pivoted to the baropposite said jaw there is 'a dog 12 whose `free end is serrated, or toothed, and behind this dog the bar 9 carries the stop, 13, against which said dog engages, or rests, when in inactive position. V

Swung from the respective cross beams 8 are the U-shaped hangers 714,14, 'the'upper ends V"of whose arms are formed with hooks which engage over said beams and a wide board 15, forming a platform., has its ends supported by said hangers 14. This platform is provided for the support of a workman in the derriclr. Y

ln pulling the rods, as 16, each rod is unscrewed from the one beneath and is then elevated by a rod elevator' 17, which is engaged Varound the upperv end of the rod and is manipulated by the cable 18 in the usual way. TWhen the rod is elevated to the required height, as illustrated in Figure 2, it is graspe(vr t i by the workman on the. platform 15 and swunginto the notch 11 and the dog 12 then swung into engagement with said rod to grip and hold thesame in said notch. rlhe elevator is then released tor engagement with the next rod to be elevated. The unit 5, with the rod suspended therefrom is then grasped by said workman and movedA over on the beam 2, out ot the way,and another empty unit 51s moved into readiness to receive the next rod lelevated and so on until all of the roos arc swung" from the hanger, as illustrated in ure1- w l, .y

.lNhen y it is desired to make up the rods again to let them down into the well the last rod elevated will be the iirst one to be lowered. In order to accomplish thisr the elevator 17 is engaged around the rod above the aw 11 and 'the rod is pulled upwardly and this will throw the dog 12 back against the stop 18 into Y released, orinactive position and the rod is then releasedkrom the jaw 11 Vand lowered and attached to the pump. The other rods in the rod hanger are then in like manner en* gaged by the elevator 17 and released from the rod hanger, as explained and lowered in the reverse order of their elevation and coupled together, each rod being coupled to the one beneath it, in lowering them into the Well. Each rod has an internally threaded box 19 on one end and an externally threaded pin Q0v on the .other end, the pin of one. rodbeing adapted to `screwinto the boX of the rod above. It is desirable that the pin of any particular rod be screwed back into the same box from which it was unscrewed, in order to Y v form la perfect lit, inasmuch as eachpin is mated With its particularl box and'might not mate or fit perfectly With some other box.

It is therefore necessary thatrods be stored on the hanger in the order in which they are separated so that they may be returned and made up in their original order, as let downy into the Well. This is'easily accomplished with the type'of hanger herein described, and

; furthermore the suspended rods Will not become entangled, or tivistedtogether, thus con"- ducing to ease'in handling. The upper ends Vof the rods, `suspended from the hanger, eX-

tend some distance above the hanger so that the conventional type of elevato'ig'adapted to engageri'ound rods, may be easily engaged around the round portion of the rod iinmediately above the hanger, in all of these re-` spects the type ofL hanger kherein described constitutes an improvement over rod hangers v now in common use. l lhat I claim is l; In a derrick, the combination With oppositely disposed end supports of a transverse I-beam Whose ends'are supported on said end supports, a plurality of rod engaging means 'of said beam each rod engaging means including a U-shaped bracket having depending arms vwhich embrace said beam, the free ends of saidarms being; inwardly turned forming` retaining' means said bracket being sldable lengthwise on said beam.
